摘要：

Neutron GEM-based detectors represent a new frontier of diagnostic devices in neutron-linked physics applications such as detectors for fusion experiments (Croci et al., 2012 [1]) and spallation sources (Murtas et al., 2012 [2]). Besides, detectors installed in HEP experiments (like LHC at CERN) are dip in a high flux neutron field. For example, the TOTEM T2 GEM telescope (Bagliesi et al., 2010 [3]) at LHC is currently installed very close to the beam pipe where a high intensity (> 10(4) n cm(-2) s(-1)) neutron background is present. In order to assess the capability (particularly related to discharge probability) of working in intense neutrons environment, a 10 x 10 cm(2) Triple GEM detector has been tested using a high flux (10(5) n cm(-2) s(-1)) neutron beam. The neutron-induced discharge probability P-Disch was measured to be 1.37 x 10(-7) at an effective gain G = 5 x 10(4). In addition, the different types of neutron interactions within the detector were fully explained through a GEANT4 simulation. (c) 2013 Elsevier B.V. All rights reserved.
